I was wondering why climbers don't use cycling helmets for climbing? is it because they aren't rated cause taking a crash at 80km/h is hectic. oh the reason why i asked is cause they are way more comfortable than regular climbing helmets. Well for me at least.

That would be because cycling helmets are designed and tested to protect your head from cycling related injuries i.e. riding into things at high speed. Climbing helmets are designed and tested to protect your head from from climbing related injuries i.e. rockfall.

I'm sorry. Really? Have you ever worn a petzl ecrin roc. I don't know what cycling helmets you've been buying but I never wore one as comfy as my climbing helmet. And I agree helmets are designed specifally for the sport you're engaging in. I certainly wouldn't cycle in my climbing helmet. Its just not designed for that. I've seen climbers wearing cycling helmets and it confuses me. But its your brain protect it how you see fit.

This is not exactly related to why people don't use cycling helmets but I thought it would be appropriate to ask here, why don't people wear climbing helmets for bouldering? I mean I have had falls while bouldering which have come pretty close to needing a helmet.

Wes bro,
Climbing helmets not only protect you from rock falls, but from you falling too. They come around the back of the head to save your pip from smacking a rock if you land on your back. Cycling helmets are aerodynamic, ending in a point, helping you break your neck when you deck it.

The different helmets conforms to different minimum standards. I am not familiar with the cycling standards but for climbing helmets the EN 12492 / UIAA 106 standard applies. Below is a graphical depiction (from http://www.theuiaa.org/upload_area/pict ... elmets.jpg) of the most critical requirements for climbing helmets. You'll see that penetration, energy absorbtion and slippage of the helmet are some of the important things that a climbing helmet needs to cater for.

Anyone know what the requirements are for cycling helmets for a comparison?

The standards for a cycling helmet is EN 1078.
From Wiki it looks like the same tests as with climbing helmets. But not tested for penetration.http://en.wikipedia.org/wiki/EN_1078
Anyone time to search for a nice graphic showing the tests?? (my quick search ended up in having to pay for a report of the detail of the tests)

Cycling helmets can only handle one impact. Maybe the main difference between the two? (Except the penetration part)

Climbing helmets are also made to absorb only one major impact, the Ecrin, Elios, Vertex, Half Dome etc have a hard shell that is durable and can withstand the knocks and bumps of normal use (I knock my head far far more when wearing a helmet than when not) but should they actually save your life they should be retired. The Elios and Half Dome have deformable foam like a cycling helmet, the Vertex and the Ecrin have small plastic pins (holding the webbing) that break under heavy impact, helping to absorb the shock.

I would not recommend reusing your helmet after a major impact, even if it looks ok.

This was the result of a ground fall (the climber was seriously injured, incl. head injuries, and flown away by a heli but recovered and is still climbing strong years later) - If it was my choice I would think carefully about using safety equipment made a for different activity just to save 500 bucks.
